A guide wire for a catheter is inserted for use into the catheter and has a wire body, a reshapeable shaping ribbon (wire material) mounted such that a part of the base end side of the shaping ribbon is fixed to the front end side (small diameter section) of the wire body and a part of the front end side of the shaping ribbon extends in the direction to the front end of the guide wire from the front end of the wire body, and a helical coil installed so as to cover both the front end side of the wire body and the shaping ribbon. The coil is divided into a first coil and a second coil, and the first coil is divided into a fine pitch section and a rough pitch section. The bending rigidity of the fine pitch section is greater than that of the rough pitch section. |
